STOCK TAG.

Application filed June 23, 1924.

T all whom it may concern:

Be it known that I, GUY Gr. GRAHAM, a citizen of the United States, and a resident of Kansas City, county of Jackson, State of Missouri, have invented a certain new and useful Improvement in Stock Tags, of which the following is a complete specification.

This invention relates to animal markers and more especially to ear tags for use in 1 marking cattle. One of the objects of the invention is to produce a cheap and highly efficient marker which after insertion in the ear of an animal cannot be removed without irreparably mutilating the tag.

Another object is to produce an ear tag which embodies the smallest number of ele ments possible and which is of strong, durable, efficient and inexpensive construction.

With the general objects mentioned in view, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which Figure 1 is a face view of a portion of an animals head and illustrates the tag embodying the invention secured in the ear.

Figure 2 is a perspective view of the tag after it has been secured in position.

Figure 8 is a longitudinal section through the tag as shown in Figure 2.

Figure 4: is a section through the locked end of the tag as shown in Figure 3.

Figure 5 is a section similar to that of Figure 3, but illustrates the locking rivet prior to the locking operation.

Figure 6 illustrates the tag in blank form.

In the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 illustrates a strip of suitable material which is bent to relatively U-shape and is formed at one of its ends with a perforation 2 and at its other end is cut and pressed out as at 3 to form a longitudinally-extending bridge piece over the opening thus formed. The bridge piece 3 in line with the opening 2, is provided with a protruding or centering and spreading cone 4.

The tag is fitted on the animals ear and a rivet 5 is inserted in the opening 2 and forced by means of pliers, not shown because common in the art, through the ear and into the opening formed by the produc- Serial No. 721,731.

tion of the bridge. The rivet 5 is formed with a head 6 larger than the opening 2, and at its other end is cylindrical and hollow as at 7, to form bevel edges for the ready penetration of the animals ear. The cone f on the bridge 3 of the tag, centers the rivet through engagement with the hollow or cavity, and upon the application of pressure by the pliers, the end of the rivet is forced to expand radially outward in all directions as at 8, thus producing a head on the enclosed end of the rivet and posi tively guarding against recessive movements thereof from engagement with the tag.

It will be apparent from a consideration of the drawing, that the bridge member not only acts as a guide to bring about the formation of the locking head on the rivet, but also conceals said end of the rivet and effectually guards against tampering with the end of the rivet in the endeavor to remove the tag from the animals ear. The bridge also minimizes the chance of the marker catching on a wire fence or the like and tearing out of the ear.

It is believed that the construction and operation of the device has been sufficiently set forth as to obviate further description of the operation. It will be apparent that I have produced a device of the character described which possesses all of the features of advantage set forth as desirable, and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim 1. A cattle tag comprising a relatively U- shaped member formed with alined perforations at its opposite ends, a bridge member formed integrally with the tag and bridging one of said perforations, and provided centrally with an inwardly-facing conical projection, and a rivet extending through said openings and provided with a cavity at one end receiving the conical projection; the ends of the rivet being interlocked with the opposite ends respectively, of the tag.

2. A cattle tag comprising a relatively U- shaped member formed with alined perforations at its opposite ends, a longitudinallyextending bridge member narrowed at its ends, and formed integrally with the tag and bridging one of said perforations, a

rivet being expanded by said projection against the outer side of the adjacent end of 10 the tag at opposite sides of the 1ongitudiwilly-extending bridge.

In Witness whereof I hereunto afiix my signature.

GUY G. GRAHAM.
